Sounds like a problem that got created with the software upgrade.
Do you have MailHosts configuered?
Also check the headers of the messages in your SpamCop Held Mail folder
Are they all addressed to yourname[at]SpamCop.net
How are you doing the test?
Forwarding the message or using IMAP to move the message?
If you are using Forwarding the test may be invalid as SpamCop may be looking at the message as coming from you, and it may view it differently dependant on how MailHosts is configuered.
Also check your White List to be sure that is not the cause of the problem.
Next thing I would do is terminate all forwarding and POPing being done by SpamCop and then redo the settings. Then re-run your test.
Please post your results.
If that does not work, then you will probably need to contact SpamCop Staff.
If you would like additional help from here, please parse and cancel both test messages and post the
Tracking URL so that we can see the differences.
Also as Andrew stated, please post the exact current setup.
Forward from account 1 or POPing account 1 from SpamCop.
Forwarding from SpamCop or POPing SpamCop
My guess is that you are using the forwarding options from both.
My setup is to forward to SpamCop from multiple accounts and then POPing SpamCop which is still working correctly for me.
